[Qt-interest] QPlainTextEdit has broken layout after hide(), show()

[Nikos Chantziaras]

I came across a strange glitch with QPlainTextEdit: When I modify it 
with insertPlainText() while the QPTE is hidden and then show() it, the 
contents are all messed up and will only show correctly is the user 
resizes the widget.  Calling update() after show() does not help. 
Calling document()->setModified() and/or document()->markContentsDirty() 
doesn't help either.

Any solutions to this?  And should this be considered a bug that should 
be reported?
